To .I1/ZZ whomV it may concern.:

Be it known that I, CLARENCE H. How- ARD, a citizen of the United States, residing at St. Louis, in the State of Missouri, have ,invented a new and useful Improvement in Locomotive-Engine Frames, of which the following is a specication.

My invention relates to a combined end sill and draw-bar ocket for a locomotiveio engine frame, and 1s in the nature of an improvement on the United States Letters Patent granted to James F. Dunn August 21, 1900, No. 656,531, for a new and improved locomotive buffer-beam.

My invention has for its object to provide a firm and extended attachment of the end sill and combined draw bar pocket to the longitudinal metallic frame-beams ofa locomotive for insuring a more erfect protection 2c to the lcylinder-heads an adjacent important parts of the engine and increasing the rigidity and resistance of the end sill to shocks from collision.

It consists in features of novelty as hereinz 5 after described and claimed, reference being had to the accompanying drawings, forming part of this specification, whereon- Figure -1 is a to plan of my improved end sill and combine draw-bar ocket with its 3o bracing and attachment to t e longitudinal metallic frame-beams (broken away) of a locoiriotive; Fig. 2, a front elevation thereof; Figs. 3 and 4, vertical transverse sections through the vdraw-bar pocket and its bracing and attachment to the frame-beams on lines 3 3 and 4 4, resipectively, in Fig. 1; Fig. 5, a vertical longitu inal section through the end sill'and draw-bar pocket on line 5 5 1n Fi 1; and Fig. 6 a similar view through the 4o en sill on line 6 6 in Fig. 1, showing its attachment with the draw-bar pocket to the adjacent end portion of one of the framebeams. (Seen in outside elevation.)

Like letters and numerals of reference deal represents the end sil which in the present case is preferably box-shaped in crosssection with its top and bottom walls parallel longitudinally, and the whole composed,

5o referably, of cast-steel inte 'al throughout;

ut the end sill a may be o yany other suitable shape in cross-section, such as channelshaped, and either straight lon itudinall -on its under side or otherwise, as eeined a vis-y able. n

` The end sill a isforin'ed transversely through its middle portion with a suitable opening 1 for the passage therethrough and play of the draw-bar b, (indicated by dotted lines,) recesses 2 being formed (or not) in the sides of the opening 1 for receiving the springs i, wzhich bear against the sides of the draw- The opening 1 communicates with the draw-bar pocket c, which projects horizoninte al therewith and located between the longitudinal frame-beams d. The pocket c may be of any suitable construction adapted to receive the inner end portion of the drawbar b, with its yoke 4, springs 5, and follower-plates 6, (indicated by. dotted lines,) which are arranged and operate in the usual wellknown manner, the outer end of the draw-bar b having the coupler 7,

Preferably from each side of and lintegral with the draw-bar b along the middle Athereof and externally thereto projects a brace or bracket e, which may be of any suitable shape in cross-section and is united at one end (preferably integrally) to the rear side of the end sill a, from which it extends, preferably, for the entire length of the pocket c, the outer side portion of the bracket e being preferably T- shaped or formed with a to and bottom upright flange 8, respective y, the flanges 8 bearing againstthe inner face ofthe corresponding frame-beam d, to which they are fixed b bolts 9 and 9', (or rivets,) as shown. Or, if esired, only one flange 8 may be used or lugs substituted therefor, according to the contour and disposition of the brackets e between the pocket c and the engine-frame beams d. Each longitudinal frame-beam d is preferably enlarged at its front end and butts thereat against the rear side of the end sill a., 'to which it is fixed by the bolts 9, (or rive,ts,) which pass through the flanges 8, (enlarged in depth thereat conformably to the end o the beam 11,) and the frame-beam d and through a web or bracket 10, which proouter face of the frame-beam d, the web 10 being either integral with the endsill a, as shown, or of separate construction bolted or riveted thereto.

By the above construction the brackets e ing along-and attachment to the sidesv of the lo itudinal metallic frame-beams d', to which't ey operate as a brace, the end sill a tally from the rear side of the end sill a and is jects from the end sill-a and bears against the being inte al with the draw-bar ocket c' and end si a and having an exten ed bear-A is reatly stren thened transversely at its mi dle and wea est portion and is practically in one piece with the frame-beams d, whereby in the event of collision its deflection thereat and consequent buckling of the frame-beams d is prevented. Moreover, by the bearing of the webs 1() against the outer sides of the frame-beams d conjointly with the bearing of the inner sides of the latter against the flanges 8 of the brackets or brace e any deflecting strain on the overhanging or outer end portions of the end sill a is transmitted to the frame-beams d and brace e byy the webs 10.

I do not limit myself to the preferable construction above described and shown on the drawings of a bracket e projecting from each side of the draw-bar pocket c alon its middle portion or thereabout, as the brac ets e may be virtually in one piece extending the entire distance between the frame-beams d below the pocket c, to which it is integrally united, my object bein to the frame-beams having the drawbar pocket and end sill as component parts thereof.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination with the longitudinal frame-beams of a locomotive, of an end sill fixed to the said beams and havin a central opening transversely therethroug for the draw-bar, a draw-bar pocket inte ral with the end sill and projecting rearwar ly therefrom between the said beams and in alinement with the said opening, a bracket projecting from each side of, and integral with the said pocket and with the end sill, the said brackets having their outer lateral .portions adapted to bear against the said beams, and means for fixing the said brackets to the said beams, substantially as described.

2. The combination with the longitudinal f frame-beams of a locomotive, of an end sill fixed to the beams and having a central open.-

to obtain a brace ing transversely therethrough for the drawbar, a draw-bar pocket inte ral with the end sill and projecting rearwar ly therefrom be- -tween the said beams and in alinement with the said opening, a bracket projecting from each side of, and integral with the said pocket, the said brackets having their outer lateral portions adapted to bear against the inner sides of the said frame-beams, and means for ixing the brackets to the said beams, substantially as described.

3. The combination with the longitudinal frame-beams of a locomotive, of an end sill fixed to the said beams and havin a central opening transversely 'therethroug for the draw-bar, a draw-bar pocket inte ral with the end sill and projecting rearwar ly therefrom between the said beams, in ahnement with the said openin a bracket projectin from each side of, and integral with the sai pocket, the side brackets having their outer lateral portions adapted to bear against the inner sides of the said beams, webs projecting from the end sill and ada ted to bear against the outer sides of the sai beams, and means for fixing the said` brackets, beams, and webs together, substantially as described.

4. The combination with the longitudinal frame-beams of a locomotive, of an end sill fixed to the said beams and havin a central opening transversely therethroug draw-bar, a draw-bar pocket integral with the end sill and projecting therefrom between l the said beams, and a race integral with,- and adapted to connect the said pocket and end sill to the said beams, part way along the sides thereof, substantially as described.

In testimony whereof I have signed my name to this `specification in the presence of two subscribing witnesses.

CLARENCE H. HOWARD.
